To ZZ l10710121 lit may concern Be it known that I, ALBERT N. CRAWFORD, a citizen of the United States, residing at Pittsburgh, inthe county of Allegheny and State of Pennsylvania, havev invented certain new and useful Improvements in Water Closets, of which the following is a specifi cation.

The present invention relates to improvements in water closets, and is designed especially to provide a device of this character with a flushing apparatus that will furnish a variable supply of water for the purposes required.'

In water closets of the sanitary type as now in use most of the closets use the same quantity of water for flushing purposes, notwithstanding the fact that the same quantity is not vnecessary in all cases.

The object of my invention is the provision of means whereby a minimum or a maximum quantity of water mayr be used, as selected, to flush the closet bowl. In this manner suticient water may be used to accomplish the purpose, using sometimes a minlmum and sometimes a maximum quantity as desired. Y

In the accompanyingr drawings I have illus trated one complete example of the physical embodiment of my invention, and a modified form of construction of the flush tank, con.- structcd according to the best mode I have so far devised for the practical application of the principles of the invention.

Figure .1 is a vertical central sectional view of the flush tanks and apparatus. Fig.

2 is a horizontal section on line 1-1 of Fig.

1. Figv 3 is a similar view at line 2 2 Fig. 1. Fig. 4 is a top plan vifew of the flush tank, showing a compartment formed with integral walls Within the iiush tank; 5 is a iront elevation of thetank of Fig. 4 with a portion of the front broken away and showing the inner compartment or tankwalls in section. Fig. G is a top plan view showing a separate tank of smaller ca acity located within the larger tank. Fig-g is a front elevation of Fig. G showing the inner tank-walls in section. Fig. 8 is a side view of a water closet embodying the novel features of my invention.

In the preferred embodimentof my invent-iones clearly illustratedin Fig. 1, I employ a flush tank 1 having formed therein a compartment 2 whose bottom 4 and sides casing is in'closed a spring pressed plunger Fig.

5 are integral with the walls of the tank 1.

The tank 1 has a perforated bottom 6 and the compartment 2 communicates with the interiorof the tank 1 through large perforation 7 in the bottom wall 4 of the inner compartment 2.v

. Within the inner compartment 2 is located a sleeve 8 formed with a iarin'gmouth 9,

vand has its threaded lower end 10 projecting through the perforation 7 in the compartmentbottom 4. Usual packing rings or ment in the perforated spiders 1`5"and 16, the former being cast integral with the sleeve,

'This tube.14 is capable of vertical'move- 8 andthe latter integral with the sleeve 17 which' is screwed on the end l() of the sleeve 8. The sleeve' 17 is provided .with a series of openings 18 establishing communication between the largetank 4and the interior of .the sleeve, and gaskets 20 are utilized to provide'twater tight joints.

The Hush pipe "2'1 vis attached at the lower threaded end 22 of the sleeve 17 by means of the union or coupling 23, a tubular portion or sleeve 24 being formed integral with the Hush pipe 21.

With-in the lower open end of the. sleeve 24 a casing 25 is threaded, and within the .bar 2G formed with a head or pist-on 27. The head 27 isv adapted to move vertically within the sleeve 24, and when at its upper position closesthe upper end of the sleeve by seating against the shoulder or ring 28, thus `closing water against exit through-the flush pipe 21. 'y

The 'under silde'of the piston or head 27 tits in a seat in the lower end of the sleeve l24l and rests on the sleeved-spider 29, be-

tween which and the rigid ring 30 on the stem 26, the spring 31 is interposed.

An extension 32 projects upwardly from the head- 27, and an adjustable head is formed on the extension by means of the screws 33 and 84, which, as clearly seen lin Fig. 1 isadapted to contact with the head 35 on the 'tubular plunger\14."

vec

les

. A float y86 actuates the usual Valve 37 'to 'and an overflow pipe 38 -is-adapted tol, carry 0H any overow from the tank 1 to the iush pipe 21 through its sleeve 24.

In the modiiication of Figs. 6 and 7 the inner compartment is formed of a separate vessel or tank 39 located withinv the large tank and suitably fastened therein.

In Fig. S the application of the device is illustrated. The plunger bar 26 is shown in contact with the lever end 40 attached to theseat 41 which is pivoted on the bowl 42 at 43.

In operation, assuming that the bowl requires a minimum amount of water to flush it, say twoy gallons, the seat is pressed and held down momentarily. Pushing down on the seat lifts the lift rod 26, against the spring 31 until the head or piston 27 con'- tacts with the shoulder 28 thus closing water against exit through pipe 21. 'Ihe'upward movement of the lift rod also causes the screw 34 at the end of the extension 32 to engage and lift the plunger tube 14 and the stem 13 with it, thus lifting the valve 12 from its seat 9 and permitting the contents of the compartment 2 to flow down into the lower part of the tank 1 and also lling the sleeve 22 above the piston 27, ywhich it will be remembered is closing the upper open end of the sleeve 24. When pressure is removed from the seat 41 the spring 31 and weight of the water cause the piston 27 to descend to its lower seat, and the contents of the lower part of the tank 1 is permitted to flow through the openings 18, sleeve 22, and

,flush pipe 21 to the bowl. The descent of the water level in the compartment l opens the water inlet valve 37, through the movement of the float valve, and after the valve 12 returns to its seat the inner 'tank or compartment again refills. Should a flushing charge equal to the capacity of the tank and compartment be desired, the seat is held deressed a longer time, and consequently the valve 12 is held suspended from its seat for a time suiiicient to permit both the tank and the compartment to lill through the move- 'ment of the ball inlet.valve as usual. When messie the tank and compartment are both filled, the ball valve automatically shuts olf the inlet ofwater.'4 New with both tank and compartment full, the seat is released, the

valve or piston 27 falls and the water from both the tank and compartment iiow down through the ush pipe as will be understood.

After this latter flushing, the compartment only, is again filled by the ball valve inlet. Having thus fully described. my invention what I' claim as my invention is 1. In a flushing apparatus the combination of a tank having a large compartment and a small compartment, a sleeve projecting through the Abottoml ofthe large compartment forming r an outlet and passing through the small compartment, a flush pipe connected to the small compartment, a valve between the tank and flush pipe, a YHeat valve adapted to seat in said sleeve having its stem. projecting downwardly, and a stem on the first valve adapted to contact with the stem' of the second valve andl lift said valve from its seat as the first valve is opened. v

v 2. In a flushing apparatusthe combination with compartments, an yopen sleeve in the lower` compartment opening in the upper compartment andprojecting below the lower compartment, a flush pipe connected to the sleeve, a valve seat between said pipeand tankanda valve to closesaid seat having an upward extension, anv outlet oat valve `in the upper compartment, a stem on the float valve, and said extension and stem adapted for contact for opening and holding open the outlet valve when said valve v seat is closed, whereby a minimum quantity. may be obtained from the lower compartment, and a maximum quantity obtained from both compartments.
